But if the assumption is that networks will always eventually totally

2^(48 - 3) = 2^45 = 35184372088832.
What will prevent unrestricted growth of the IPv6 table if operators
push everything out to /48 "to counter hijacks" or other misguided
reasons?
Expecting that the Internet would ever operate at maximum de-aggregation
is unrealistic. There are too many checkpoints to make that a feasible
possibility.
It's not an outcome I would spend any brain cycles on, unless as an
academic exercise.
